SPECIFICATION forming part of Letters Patent No. 727,868, dated May 12,1903. Application filed January 10, 1903. Serial No. 138,551. (Nomodel-l To all whom it may concern.-

Be it known that I, GEORGE WEILER, a citizen of the United States, and aresident of Uniongrove, in the county of Racine and State ofWisconsin,have invented certain new and useful Improvements inDough-Raisers; and I do hereby declare that the following is a full,clear, and exact description thereof.

My invention has for its object to provide simple, economical, andportable dough-raisers, organized to also serve as warmers for flourthat is to be mixed with raised dough,

said invention'consisting in certain peculiari-.

ties of construction and combination of'parts hereinafter particularlyset forth, with reference to the accompanying drawings, and subsequentlyclaimed.

Figure 1 of the drawings represents a ver tical longitudinal section ofa dough-raiser and flour-warmer in accordance with my invention; Fig. 2,a vertical transverse section of the same, and Fig. 3 a perspective viewthereof.

Referring by letter to thedrawings, A indicates a preferably sheet-metalbase having openings therein and provided with legs I), that may beflanges of said base. Set on the base is a shell B, that is alsopreferably of sheet metal and of oblong shape. Surmounting the shell isa perforated top 0, that is preferably of the same material as saidshell,

the latter being preferably provided with flanges that oppose said baseand top. Boltrods D extend through the base and top, and nuts 0 are runon the rods to clamp said base and top against the shell, the wholeconstituting a box.

The box-top C is provided with guides d for perforated slides E, andstems 6, depending from the slides through slots in said'box-top to comeinside the box-shell B, are in connection with rods F, thatextendthrough ends of said shell, adjustment of the slides, by means ofthe rods, serving to control the perforations in said top.

The shell or body B of the box is provided with a preferably mica-glazeddoor G, and a thermometer H is shown inside of said shell opposite thedoor. Handles f are also provided in connection with the shell.

Set in the box on its base A is a lamp I, and air to support combustionof the lamp is admitted through the openings in said base, the flamebeing regulated according as the thermometer shows from time to timethatv the temperature in the'heater is higher or lower than apredetermined degree.

Dough to be raised and flour to be warmed are set in pans on top'of thebox above described, the slides E being adjusted to regulate the area ofopenings of the perforations in the top of said box, more heat beingrequired for the dough than for the flour.

Having thus described'my invention, what I claim as new, and desire tosecure by Letters Patent, is-

' A portable dough-raiser consisting ofa box mounted 0n legs andprovided with bottom openings, top perforations and a body-door;

GEORGE WEILER.
